hi Lulz,

Symantec, McAfee, Kaspersky, are notorious for causing internet connectivity issues, especially when they expire. They don’t tell you that. This is a well-known secret in the IT community, so you need to ensure all traces of NIS is totally gone: http://singularlabs.com/uninstallers/security-software/

IF you are running another Symantec product, then use of either/all Norton/Symantec removal program(s) will remove that also. You may need to re-install that program or maybe choose another product to replace it.
